What is Polyurethane (PU) Grouting?

Polyurethane Injection grouting is a waterproofing technique that involves creating a polyurethane mixture whereby when this mixture is inserted with pressure into the cracks of a structure, the mixture will react and in turn expand and toughen. It is used to stop water flowing through structural joints and cracks.

PU grouting is mainly used to restore cracks and repair water damages that have been done to walls, flooring, etc. It prevents cracks from leaking continuously and it is used to maintain the structure’s operational integrity.
